In example A1, the two conformists start off with the same style; the nonconformist is different. This world is stable. The conformists are happy because they are the majority. The hipster is happy because she’s in the minority. People stick with their current style.
In example A2, it takes some shuffling around before the world settles down. Two of the conformists start off normcore; the other conformist is punk; the hipster is also punk. From the perspective of each normcore conformist, the consensus seems to be punk (they don’t count themselves). They both decide to be punk in the next turn.
